Retrosynthetic analysis

Definition

Retrosynthetic analysis is a problem-solving technique used in organic chemistry to deconstruct complex molecules into simpler precursor structures. This method allows chemists to plan the synthesis of target compounds by working backward from the desired product to identify feasible synthetic routes and starting materials, emphasizing strategic thinking in the design of synthetic pathways.
